Hi!
Is there any chance that future RAP releases can embed OLE objects like
SWT (package org.eclipse.swt.ole.win32)?

Magnus

Hi Magnus,

this sounds really strange to embed OLE in RAP but I really see that
some people would need this. As I'm not the best guy to answer questions
regarding Microsoft technology I'll just try to give some feedback from
my view point.

As far as I know OLE it's just some ActiveX components playing together.
First problem is (same in SWT) that this will just run on Windows
Platforms. Additionally with RAP only in Internet Explorer.

Theoretically you can write your own custom widget which shows the file
in an <embed> tag to so the file gets loaded by the corresponding plugin
on the client computer. Afaik since Office 2007 that is even impossible
because the standard installation will open the file in an external
window (which can be hijacked by modifying the registry - see MS
KnowledgeBase for more information).

But after displaying the whole stuff there is a need for interaction
between the ActiveX controls and the RAP clientside
(Javascript/Qooxdoo). And i really have no hope that something like this
would work.

BUT these are only my thoughts about the whole thing. If someone from
the community has more knowledge about OLE, ActiveX and browser
integration feel free to tell us about it so may come up with a
solution. Maybe not in the near future but some day ;-)

Client-Client-communication can be avoided if the ActiveX calls certain URLs
where a RAP-ServiceHandler is registered. Data can be exchanged by
parameters (either POST or GET). The problem which remains is updating GUI
from inside the ServiceHandler. This can be achieved by using UI callbacks
and a polling mechanism in the gui code which reacts to changes to a
container-object (which is modified by the ServiceHandler).

Regards,
Stefan.

Hi Benjamin!
I expected such an answer, anyhow, thanks for thinking about it and this
great project :-)
